That freebore issue is gun dependant and often more hype that truth. Example. The Taurus Judge and the Smith And Wesson Governor both take 410 shotgun and 45 Colt. The smallest one takes the 2.5 inch 410 shell, that means the cylinder is actually 3 inches long, the Taurus Magnum version is 3.5 inches long. The natural concern was that the free bore or free space in the cylinder in front of the 45 Colt was believed to be such that it would destroy accuracy. That is theory, not science. Gun writers make that stuff up and we all just naturally take it as gospel.
The accuracy of a bullet in a revolver is not much effected by the cylinder, it is more related to the bullet entering the forcing cone, and sealing in the barrel. The barrel then imparts the spin and determines the level of accuracy. Those two Guns can be expected to shoot under 3 inch groups at 25 yards. They are snub nose Guns.
Now, the Governor also takes the 45 acp in moon clips. The 45 acp looks tiny in that 3 inch cylinder, but the science is the same. The forcing cone and barrel determine most of the accuracy,. Again, about 3 inch groups at 25 yards, the same standard law enforcement sets for duty Guns.
Now, that long cylinder gives the explosion chamber more space and more time in that chamber, that allows more gas to escape at the cylinder/barrel gap. What that does is rob velocity. In my 1911 I can expect maybe 850 fps with standard ball ammo. Firing that same ammo in my Governor loses about 100 fps. In other words only about 750 fps. The most accurate and powerful 45 Colt I have found with standard pressure loads is the Hornady. Lever Evolution rounds. They get near factory velocities and shoot under 3 inches. These Guns have fixed sights and short barrels, not much better accuracy can be expected.
The Hornady load is my go to load for all 45 Colt handguns. I do have a Bisley, which takes the bear loads with power equal to 44 mag, a totally different animal.
Just saying, the long cylinders do not necessarily affect accuracy. I have also found, that just like every other gun, some ammo shoots very accurate and some does not. So, do not believe what people may say if they do not own them. I have six guns that shoot 45 Colt and load them from mild to wild. The real measurable difference at 25 yards is maybe 1 inch, and that is comparing a 5.5 inch Bisley Blackhawk to a Smith and Wesson Governor with a 2.75 inch barrel. FWIW.
